Product Details

The KYB Gas-a-Just 551126 is a high-pressure monotube shock absorber designed to deliver superior performance and control compared to traditional twin-tube designs. This advanced shock absorber provides instant, automatic adjustment to your driving demands while completely eliminating fade caused by aeration.

Monotube Performance Advantages:

  • Dual-chamber design separates hydraulic fluid from high-pressure nitrogen gas for optimal performance
  • Air-free hydraulic piston and valve chamber ensures precise responsiveness and control
  • High-pressure nitrogen gas chamber with floating piston maintains consistent damping
  • Instant automatic adjustment to changing road and load conditions
  • Fade-free performance under demanding driving situations
  • Comfortable ride quality during normal driving with performance on demand

The Gas-a-Just serves as both an OE monotube replacement and a performance upgrade for vehicles originally equipped with twin-tube shocks. The monotube design's separated working chambers deliver the perfect balance between everyday comfort and enhanced performance when you need it most.

Thanks

good so far

Receive the item very quickly but I had problems with vehicle and was not able to use merchandise so I am going to return for refund

Great service. Super fast shipping. Item was as ordered.

First time, we will see

Thank you for having the best price I could find after missing out on Black Friday deals from sites I normally shop. I will definitely keep you in mind for future purchases.

Great

Best price I found anywhere!

Good fast shipping. Easy ordering.

great prices.

I am glad I found Autoplicity! Great prices, fast shipping, and excellent customer service. Already looking at other items to purchase from them. I highly recommend using Autoplicity!

Great price and easy ordering. Cant wait for my nudge bar.

Very satisfied. Good price and quick delivery.

Great prices, quick ship thanks!

The price is right but shipping cost is high. I bought a transmission seal for $12.91 and shipping was $13.31. The box it shipped in was about 10 times bigger than the part itself. Reduce the box and reduce my shipping cost please ! Else than that the part was in good condition, it was packed right and shipping time was reasonable.
